Andy's total bill for lunch is $20. The cost of the drink is 15% of the total bill and the rest is the cost of the food. What pe

Sonbull [250]

Hi there! So Andy's total lunch bill was $20 and the drink was 15% of the bill. Percents are parts of 100 and 100 - 15 is 85. That means 85% of the total bill was Andy's food cost. Let's multiply 20 by 85% ti get the cost of his food. 20 * 85% (0.85) is 17. Andy's food costed $17. Here are the answers broken down to be easier to read.

Percent of Andy's bill with food: 85%
Cost of food: $17

Use the annual compound interest formula to find the amount in the savings account at the end of the time period and then find t

icang [17]

Answer:

$9,216 in account $1,261 interest.

Step-by-step explanation:

The compound interest is given by:

$a = p(1 + \frac{r}{n})^{nt}$

P = Principal

r = rate

n = Number of times interest is compounded per unit t

t = time

so:

$a = 8000(1 + \frac{0.05}{1} ) ^{1 .3} \\ a = 9261$

therefore, the answer is:

$9,216 in account $1,261 interest

Answer:

$m =\frac{y_2 -y_1}{x_2-x_1}= \frac{5425-3733}{3-0}= 564$

Now we can use the value for 1994 and we can find the intercept like this:

$3733 = 564*0 +b$

And solving for b we got:

$b = 3733 -0= 3733$

So then oir model would be given by:

$y= 564x +3733$

Option C

Step-by-step explanation:

For this case we want to create a linear function for the the value of the investment in the vear x, where x =0 represents 1994.

We know that for 1994 (x= 0) the value is y = $3733 and for 1997 (x=3) the value of y = $5425

We want to find a model given by:

$y = mx +b$

Where m is the slope and b the intercept. We can find the slope with this formula:

$m =\frac{y_2 -y_1}{x_2-x_1}= \frac{5425-3733}{3-0}= 564$

Now we can use the value for 1994 and we can find the intercept like this:

$3733 = 564*0 +b$

And solving for b we got:

$b = 3733 -0= 3733$

So then oir model would be given by:

$y= 564x +3733$

Option C
